MOLD -FORMAKING PAPER-BOARD BURIAL-GASKETS.

SEEGIFCATJON forming part of Letters Patent'No. 708,075, dated September2, 1902.

Application filed October 24, 1900. Serial No. 34,177. (No model.) I

T0 a/ZZ whom/ it may concern:

Beit known that I, ELISHA A. POST, a citizen of the United States,residing at Allegan, in the county of Allegan and'State of Michigan,have invented certain new and useful Improvements in Molds for MakingPaper- Board Burial-Gaskets, of which the following is a full, clear,and exact description, referencebeing had therein to the accompanyingdrawings, in which- Figure l is a perspective View of the complete inoldclosed on a casket-body; Fig. 2, an end elevation thereof with the sidesofthe mold shown in dotted lines; Fig. 3, a vertical transversesectional view through Fig. 1;

Fig. 4, a plan View of a modified form of the mold, and Fig, 5 an endview of Fig. 4. Fig. 6 is a detail View of aslight modification.

This invention has relation to an apparatus for manufacturing that classof paper` board burial-caskets covered by my Patent No. 668,883, datedFebruary r26, 1901; and the object of the invention is to provide asimple apparatus for shaping the blanks or sheets of which the casket isconstructed, as more fully hereinafterset forth.`

The apparatus consistsof a base-board o., shaped to correspond to thevbottom or base of the casket, this base-board being provided near eachend with a vertical post @threaded at its upper en d and provided With aclampnut c. Hinged to each sidev of this'base is one side d of the mold,the end sections d of this side being curved and hinged so that when thetwo sides are locked together in a vertical position the endsectionsconform tov the curvature of the ends of the base and the- Thiscore or plunger is made slightly smaller all around than the interior ofthe mold, suciently to accommodate the Walls of the casket h. Fastenedto the upper side of the core or plunger is a pair of transverse barsil, whose separately.

l ends extend outward beyond the sides` d (when the same are folded up)and are threaded Afor the reception of a crank-nutj. The upper edgesofthe sides d are provided with upwardprojecting plates or straps lo,between the upper ends of which the threaded ends of the'barsvj projectwhen the sides are folded up against the inclosed casket. By-means ofthesedevices the hinged sides may be drawn tightly up against theinclosed casket and be held in place while the casket is drying andsetting.

f In the modification shown in Figs. 4 and 5 the end of the mold isvshown polygonal in shape, each one of the sides or facets consisting ofa separate plate having a separate hinge connection to the base-board,so that they may be `closed up against the casket These end pieces aredrawn and held tightly up against the end of the casket by any suitablemeans, preferably by means of suitable bolts Z, 'swivelly connected tothe top of the core or plunger and projecting outward over the topedges4 of the plates, each of the bolts beingprovided with a clamp-nutwhich is adapted to engage a notched upwardextending plate or strap m,attached to the exterior of the section.

The casket is built up of laminae of paperboard and hydraulic cementalternating with each other,.and the blanks are preferably shaped asshown in my former patent, hereinbefore mentioned. In making Gasketshaving thick Walls the core or plunger is removed from its post and thesides of the mold folded down, as shown in dotted lines in Fig. 2. Theblanks after having been properly coated with cement are then placed onthe base-board, each blank having been perforated to receive the postsor pins b. When sufficient blanks have been put in place to form theWalls of the desired thickness, the core or plunger is placed on thepins or posts and clamped down on the blanks. Then the blanks one by oneare bent up and around the core or plunger, after which the sides of themold are swung up and clamped by the bars 1l and their crank-nuts. Thenthe end portions of t-he blanks are folded in around the end of the coreor plunger, their abutting edges being properly adjusted. Then thehinged end sections d are swung into place against the ends of thecasket and ICO are securely clamped by their bolts f. The casket is thenallowed to remain in the mold until it properly drys and hardens.

In making caskets which have comparatively thin walls the operation isas follows: The sides of the mold are clamped in place upon the base b vthe end bolts f. Then the blanks are placed upon or in the mold and arepressed down into the same by means of the core or plunger. Then thenuts c are screwed up tight, as likewise are the cranknntsj. When thecasketis removed from the mold, the perforations made for the passage ofpinsl) are closed by suitable plugs and cement.

Instead of employing crank-nutsj to draw the sides up against the casketit is obvious that I may employ any other suitable devices-such, forinstance, as a cam or eccentric device n, journaled in the projectingend of the bar t' and bearing upon the washer o, which latter restsagainst the outer surface of the plates m.

It Will be understood that the cover and the panels of the casket are tobe made in substantially the same manner.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

l. A mold for making paper-board burialcaskets and the like, consistingof a basei board, sides hinged thereto and adapted to be' connectedtogether at their ends, the posts rising from the base within the moldand threaded at their upper ends, a core or plunger fitting down oversaid posts and within the mold, and clamp-nuts on the upper ends of theposts, substantially as set forth.

2. A 'mold for forming laminated paperboard Vessels, `such asburial-caskets, a base provided with a pair of vertical posts, onerising from either end, a plunger or core fitting down over these postsand having its exterior shaped to conform to the interior of the casket,means for clamping the core or plunger down upon the base, hinged sidesconnected to the baseand conforming to the exterior of the casket.

3. A mold for forming paper-board vessels, such as burialcaskets,comprised of a base, a pair of hinged sides, each of which is providedwith a hinged section at each end, means for clamping the end sectionstogether, and a removable core.

In testimony whereof I hereunto affix my signature, in the presence oftwo Witnesses, this 22d day of October, 1900.
